serious problem

[speedminded]

looks like a simple bolt extractor should work...but you will have to get an extension shaft to fit down the head to get to the plug...

Something like this if you can find one big enough...

...but it might be kinda hard to keep it centered while trying to drill into the remaining spark plug threads.


There should be a cone shaped tool that you can drop in the hole and lighly hammer it in to bite then turn counter clockwise...maybe something like a router bit? The only problem will be trying to grasp the shaft (that's what she said ) bc i'm pretty sure they are all rounded vs. being hex shaped.
